# Verify UFS support
To check whether your Linux kernel supports the [UFS filesystem](http://en.wikipedia.org/wiki/Unix_File_System) you may execute the following command:
$ cat /proc/filesystems
nodev sysfs
nodev rootfs
nodev proc
.
.
.
ext3
nodev usbfs
vfat
**ufs**
The keyword `nodev` in the first column means that filesystem does not require a block device to be mounted, that's why it is also called [virtual filesystem](http://en.wikipedia.org/wiki/Virtual_file_system). The support is either compiled inside the kernel or as a module:
$ ls -l /lib/modules/2.6.21-ARCH/kernel/fs/ufs/ufs.ko
-rw-r--r-- 1 root root 84828 2007-05-25 20:11 /lib/modules/2.6.21-ARCH/kernel/fs/ufs/ufs.ko
# Mount
In order to find the device that corresponds to your FFS partition, run:
1. sfdisk -l
